About water soluble fertilizer What is water-soluble fertilizer? Water-soluble fertilizer is a new type of fertilizer that can be completely dissolved in water developed in China in recent years. It is a fertilizer that is soluble in water, such as industrial grade diammonium phosphate, urea, potassium chloride, etc., scientifically proportioned according to a certain ratio, and added boron, iron, zinc, copper, molybdenum and chelated trace elements. The new production process combines a fertilizer that can be completely dissolved in water. It can be fertilized by irrigation and drip irrigation water-saving agricultural facilities. It has the characteristics of high fertilizer efficiency, fertilizer saving, labor saving and increased production. (2) Moderate element water soluble fertilizer: generally refers to calcium, magnesium, boron, silicon and other ingredients. Among them, calcium fertilizer mainly uses water-soluble inorganic calcium salt and chelated calcium. The raw materials of the product may be calcium chloride, calcium nitrate, calcium ammonium nitrate, calcium acetate and calcium chelated with organic substances such as EDTA, citric acid, amino acid and sugar alcohol; Magnesium mainly uses water-soluble inorganic magnesium such as magnesium chloride and magnesium sulfate; silicon mainly uses sodium silicate as a source. Because it is alkaline and easily reacts with calcium, magnesium, zinc and iron ions to form flocculent precipitates, it is generally used alone. . (3) Functional water-soluble fertilizer: As the name suggests, it has a special effect of water-soluble fertilizer. For example, plant growth regulator type water soluble fertilizer, such water soluble fertilizer added gibberellin, naphthalene acetic acid (sodium) and other substances with biological growth regulating function; fertilizer type water soluble fertilizer, such water soluble fertilizer in addition to the nutrients necessary for plant growth In addition to the elements, a certain number of different types of pesticides and herbicides will be added. In addition to promoting the growth and development of crops, the occurrence of pests and weeds can be controlled. It can usually be divided into special fertilizers for weeding, special fertilizers for sterilization, special fertilizers for insecticides, etc. In addition, the water soluble fertilizer can also be divided into amino acid water soluble fertilizer, humic acid water soluble fertilizer, sugar alcohol soluble fertilizer, alginic acid water soluble fertilizer, sea urchin water soluble fertilizer and the like. Some water soluble fertilizers do have the effect of controlling pests and diseases, but not all water soluble fertilizers have significant effects on pest control. At the same time, from another angle, water-soluble fertilizer can directly supplement the nutrients needed for growth, and to a certain extent, it will enhance the resistance of plants, thereby reducing the probability of disease occurrence and effectively reducing the occurrence of physiological diseases. Water-soluble fertilizers have a wide range of applications, and accordingly, there are many application methods and methods. In the well irrigation area, water-soluble fertilizer can be used for equipment fertilization, and the water-saving agricultural facilities such as sprinkler irrigation and drip irrigation can be combined with the fertiliser to achieve the effect of water and fertilizer integration, and at the same time, it is not subject to terrain restrictions, such as slope land and depression. As long as the irrigation system is designed to be reasonable, it can directly transport fertilizer and water to the root of the crop, improve the utilization of water and fertilizer, increase production and increase efficiency, and achieve semi-automatic, automatic management and save manpower. This is the best way to apply water-soluble fertilizer. In the channel irrigation area, the method of flushing can be used to pour the fertilizer into the irrigation water in a certain proportion in the irrigation inlet. The operation is simple but the quantitative is not accurate. In the fertilization process, the liquid fertilizer should be uniformly distributed according to the irrigation amount and the irrigation time. Pour into the irrigation water and master the dilution factor of the fertilizer. It is generally recommended that the dilution factor of the water-soluble fertilizer be 1000-1500 times. In arid areas, water-soluble fertilizer can be used as foliar fertilizer, and foliar fertilizer can provide nutrients for crops, and the leaves can be directly absorbed and utilized. At the same time, foliar fertilizer can also be flexibly matched with drought-resistant anti-reverse reagents and fertilizer synergists to improve crop stress resistance and nutrient absorption. However, in the operation process, attention should be paid to the fertilizer concentration, and it should be sprayed strictly according to the instructions. If the concentration is too high, the blade will be damaged. The spraying is generally diluted 500-800 times. For a long time, the three major elements of nitrogen, phosphorus and potassium have been considered in the process of crop fertilization. However, there is little attention to the medium and trace elements, which depends on the soil supply. Year after year, the trace elements in the soil are hollowed out. It can no longer meet the needs of crop growth, and it will also affect crop growth. Therefore, it is necessary to pay attention to the results of soil testing, and constantly search for nutrient short plates in crop growth. When applying liquid fertilizer, mix with medium and trace element fertilizers, and timely supplement the crops with nutrients and fill short plates. I want to couple water and fertilizer efficiently. In practice, some experts concluded that “the root is the mouth of the seedling, and the water is the fat leg.†Water plays an important role in the migration of fertilizer. The fertilizer can only reach the root of the crop and is absorbed by the crop. Pay attention to water and fertilizer coupling when applying liquid fertilizer. If the irrigation amount is too large, excessive irrigation will be formed. The fertilizer dissolved in the water will continuously move down with the infiltration of the irrigation water, and eventually exceed the range of root absorption, and the fertilizer nutrient will be lost and waste. Too little water can not only meet the crop's demand for water, but also cause the fertilizer concentration to be too high, and it will accumulate on the surface of the soil, causing the roots of the crop to be burnt, resulting in "burning seedlings". Only the right amount of irrigation can meet the water and fertilizer demand of the crop. At the same time, the nutrient solution is evenly distributed around the root of the crop, neither burning or losing, but also shortening the migration distance of nutrients in the soil, promoting the absorption of nutrients by the crop, and achieving water and fertilizer. The purpose of synchronization and efficiency. Disclaimer: Some articles on this website are transferred from the Internet.

Peptides Powder is also called Nano Oligopeptide Collagen (OCO, Nano active Oligopeptide Collagen, or Nano Collagen for short), also known as Oligopeptide, micro peptide, short peptide. Small peptides generally refer to oligopeptides composed of 2-3 amino acids, with an average molecular weight of about 300 daltons. The final products of protein (collagen) digestion in the digestive tract are usually small peptides rather than free amino acids. Small peptides can be completely absorbed and enter the blood circulation in the form of two or three peptides. Small peptides play an important role in protein nutrition.

What are the classifications of water-soluble fertilizer products? (1) A large number of elemental water-soluble fertilizers: mainly one or more of nitrogen, phosphorus and potassium. The nitrogen fertilizer may be an organic nitrogen source such as an amide nitrogen fertilizer, an ammonium nitrogen, a nitrate nitrogen or an amino acid, and the raw materials may be urea, ammonium nitrate, potassium nitrate, ammonium chloride, amino acid, etc.; the phosphate fertilizer mainly uses orthophosphate and metaphosphate. Polyphosphate, etc., generally used potassium dihydrogen phosphate, dipotassium hydrogen phosphate, ammonium phosphate, phosphoric acid and some metaphosphates and polyphosphates; Potassium fertilizer is generally selected from potassium nitrate, potassium dihydrogen phosphate, potassium sulfate Wait for raw materials.
